The Goodman 10123519 Manual Reset Limit Switch is a genuine OEM high-temperature safety cutout for the GKS91155DXAF gas furnace. Mounted on the heat exchanger or burner assembly, it opens the control circuit if the furnace overheats — protecting against cracked heat exchangers, restricted airflow, and fire hazards. As a manual reset device, it will not auto-recover, forcing service attention after a trip.

Specifications

  • Part number: 10123519
  • Type: Manual reset high-limit / rollout switch
  • Contacts: Normally closed, open on overheat
  • Reset: Manual push-button
  • Compatible model: GKS91155DXAF

OEM vs. Generic

Limit switches are trip-temperature specific. This genuine Goodman switch carries the exact factory cutout setpoint for your furnace, so it protects at the right temperature without nuisance trips. Generic switches with mismatched ratings can either trip prematurely or — far more dangerously — fail to trip during a genuine overheat event.

Installation Difficulty

Easy. Disconnect power, remove the mounting screws, transfer the two wire terminals, and secure the new switch in the same orientation. If the original switch tripped, always diagnose the underlying cause (dirty filter, blower fault, or blocked vent) before returning the furnace to service — a licensed technician is recommended.
